Model Haus (
http://www.modelhaus.com) makes a simple resin kit of the Tucker for $70.
Includes four door body with hood molded in, interior tub with separate bench seat, dash, steering wheel and column, front bumper, grille, rear bumper and grille, headlights, taillights, hubcaps, wheel backs, tires, chassis, glass. There is no engine. It's no Monogram or AMT in terms of detail, but it's close.
He used to make an interesting custom Tucker Sedan Delivery which I bought from him at a show years ago, but I don't think he has any of those anymore.
